First of all, if you haven't already, I'd give some serious consideration to picking up Doom Resurrection [App Store] as today is the final day of the $2.99 sale. If you need some help clicking the "Buy Now" button, check out our review of the game.
Doom Resurrection is an on rails shooter that utilizes the graphical assets from Doom 3 to creating a gameplay experience that feels like a Doom game, despite the inability to control your character's movement. Since the $2.99 sale started, more and more people who were initially hesitant about the rails aspect of the game have seemed to since come around to enjoy Doom Resurrection for what it is, rather than what it isn't.
Over the weekend, Doom Resurrection 1.1 landed, bringing a new bonus map and a challenge mode with 40 available challenges. I completed the original version of the game shortly after it was released, and challenge mode has definitely breathed some new life in to Doom Resurrection for me as it once again has first page icon status on my iPhone.
Challenges range from scoring, accuracy, speed, and other goals. For instance, the first challenge asks you to score at least 300,000 in the first level. Each kill you make without taking damage increases your scoring multiplier that resets back to zero as soon as you get hit. Reaching (or exceeding) the target score requires you to maintain a score multiplier, which will involve some memorization of the levels to be prepared to take out some of the surprise attacks before getting hit. Another challenge that uses the first level of the game has you beating the section with 100 health, 75% accuracy, while grabbing all secrets and items.
The new bonus level is called "Gooey Reactor" that is absolutely loaded with all kinds of enemies throwing things at you. I've been slowly progressing through it on the marine difficulty level. I've got to seriously tip my hat to anyone who can beat the new level on the nightmare difficulty level, as four hits basically kills you and there isn't ver much health spread around.
The new update combined with the $2.99 sale has rocketed Doom Resurrection up to the seventh spot on the overall App Store top ten. At the sale price, Doom Resurrection provides a significant value, and an even greater one if they continue adding new levels and challenges.
